Device and method for hardware-based data encryption with complementary resistive switches

Abstract

An encoder for encoding an input binary value of a binary input data sequence by generating an output current of an output current signal is provided. The encoder includes a control module and a switchable resistive element. The switchable resistive element is configured to either be in a first state or in a different second state depending on a first input voltage at a first point in time and depending on a second input voltage at a later second point in time.The control module is configured to apply the first input voltage to the switchable resistive element at the first point in time so that the first input voltage depends on the input binary value.

AI Technical Summary

Benefits of technology

The patent describes an encoder and decoder for encoding and decoding binary data. The encoder uses a switchable resistive element that can be in different states depending on input voltage. The decoder uses the output current generated by the encoder as an input current. The system can also include a control module that applies different input voltages to the switchable resistive element at different points in time. The technical effect of this invention is to provide a more efficient and accurate way to encode and decode binary data.

Problems solved by technology

However, a considerable time and computing effort and the associated increased energy consumption are disadvantages of software-based full disc encryption.

A software-based method will no longer be practicable in the future, given the expected rapidly growing amounts of data having to be processed.

The challenge in realizing a PUF is to find a physical object (encryption hardware) that has an unpredictable individual property.

At the same time, however, the individual properties of memristors depend heavily and uncontrollably on the manufacturing process and are therefore unpredictable.
